On a snowy two-lane highway, you come up behind a snowplow that spreads sand and throws up a cloud of snow. What should you do?
A snowplow spreads sand and produces a snow cloud on a snowy two-lane road. A approaches behind; no following-distance bracket or passing path is present.
Correct answer: Stay well back, and pass only when you can see the whole plow
Why
Snowplows move slowly and can make whiteout clouds that hide the road. Watch for their flashing white, yellow and blue lights. In neighborhoods, plows may back up to turn around, so give them extra room.
